Artist Frank Boelter got this idea when fiddling with an empty milk carton at breakfast: to make and sail a gigantic paper boat made with "Tetrapack," the material used for packaging milk!

The £110 boat is 30 feet long, weighs 55 pounds, uses a 170-square-metre piece of Tetrapack paper, and took only two hours to construct. Boelter said it will survive forty days before it disintegrates into a wet, sinking mass.
